8.2: Capacitors and Capacitance

A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...

Series resistors (video) | DC Circuits | Khan Academy

One way to figure this out and to simplify the circuit is to replace all three of those resistors with a series resistor, RS, and that is, as we said here, is the sum, so it''s 100, plus 50, plus 150. And that adds up to 300 ohms. So that''s the value of …

Physics Tutorial: Series Circuits

In series circuits, the resistor with the greatest resistance has the greatest voltage drop. Since the current is everywhere the same within a series circuit, the I value of ΔV = I • R is the same in each of the resistors of a series circuit. So the voltage drop (ΔV) will vary with varying resistance.
